High Piston Adjustable (Extended Height:18.5''/28.74'') Hydraulic Gas Lift Cylinder,Universal Size Replacement for Most Stool Chairs,Smooth and Noiseless(Black)

Bought this to replace a worn out piston on a drafting chair. I had a heck of a time getting the old one out, but that's more of an fyi to anyone looking to replace it. This one fit right in the old base and works as it should. Hopefully it will last longer than the original piston.

This was exactly what I needed. I would suggest renaming it as I didn’t find it searching Amazon, but found on a google search. Maybe barstool hydraulic lift replacement. May be better than the original that the stool came with - this is the replacement you need!!

Getting the old one out of the bar stool was a little tricky. Once that was done, I could get the measurements and model info., to search and ultimately settle on this one. Glad I did. It's perfect.

I’m 6’5” - it transformed my stool into a brand new one made for me. It’s also of higher quality than my previous cylinder with smoother suspension and turning.

I wanted my gaming office chair to sit higher. I purchased this and it fit perfectly!! I highly recommend if you want to sit up higher than the average office chair and you have a adjustable heighten desk. I am 5’5 and well off the floor now, with this piece on my chair, with it at its lowest height. At its highest height the chair is extremely high in the air, like mid room high.**1st picture is the chair at its lowest.**2nd picture is the chair at its highest.

This chair cylinder was purchased November 2, 2023, and worked fine until February 9, 2024 this is when it started losing its ability to stay up. And this only had a 30 day return. Not worth buying if it’s only gonna last three months.

I wanted to take a short stool and make it taller. This did just that. Its what i was looking for! It’s ergonomically important to get the height of your seat correct.

This item is made in China and as usual, these items come with a surprise. When I installed the item, the seat of my chair went chest high. I could not lower the seat down at all. The cylinder emitted a liquid substance that flowed down the outer surface of the piston.
